Hee. It's one of my most favoritest movies. I do wonder how much scarier it would have been in a theater. On a big screen. In the dark. (I was like 12 or 13 when it came out.)

Actually, speak of the devil, they talk about it in the Cam Gigandet/Twilight interview:

MTV: There are old stories of Anthony Hopkins sneaking into theaters when "Silence of the Lambs" was playing. He'd wait until a scary Hannibal Lecter moment in the movie, then tap a viewer on the shoulder and say, "Hello," just to freak them out.

I'm pretty sure I would have fallen over and died.
